As a destruction method of chemical weapons, the controlled detonation system named DA VINCH was developed. Over 99.9999 % Chemical Warfare Materials (CWM) Destruction Efficiency (DE) or DRE (Destruction and Removal Efficiency) is achieved solely by detonation processes.

The high pressure of 10 GPa and high temperature of 3,000 K generated by detonation are the causes of high efficiency and the phenomena is completely different from that by incineration process. Optimization of amount of donor charge to the CWM is also studied.

CO and H2 gases in detonation product gas are treated by a plasma oxidizer.
